socket module does not have if_nametoindex method #870
Description
Activity
The NDK's include/net/if.h indicates that the underlying libc function isn't available until API level 24:
if __ANDROID_API__ >= 24 struct if_nameindex* if_nameindex(void) __INTRODUCED_IN(24); void if_freenameindex(struct if_nameindex* __ptr) __INTRODUCED_IN(24); #endif /* __ANDROID_API__ >= 24 */
Since we currently compile Python against API level 21, the
socket.if_...functions won't be available. I'll add this to the documentation.What do you need this function for?

on May 10, 2023 @mhsmith Thanks for answer. I need this functions to wrap some python protocol library(reticulum) in kotlin. How can I fix it?
That depends on how the library uses the function. You might be able to get away with a minimal implementation like this:
import socket def if_nametoindex(if_name): raise OSError("not implemented") socket.if_nametoIndex = if_nametoindex
Or if the library needs the function to return real information, perhaps you could implement it using ctypes to call the underlying libc function.
Adding to the next milestone because it's better for these functions to return OSError as documented, rather than AttributeError, which user code is unlikely to catch.
Thanks a lot!
